Despite their name and dramatic, remarkably parallel linear sand dunes, this "sandy" desert is actually slightly wetter than the central part of the country. Even the driest parts get at least 10 inches (25 cms) of rain a year, and some small streams flow with fresh water after heavy rains.

But intense heat evaporates the moisture almost as quickly as it falls. The region supports many unique plant and animals species specially adapted to the difficult conditions.

Local Species
Found here is the Livistonia palm - one of the spectacular plant species adapted to desert conditions. A number of mammals survive here, including Red kangaroo (Macropus rufus), the endemic little Red antechinus (Dasykaluta rosamondae), Marsupial mole (Notoryctes typhlops), and Bilby (Macrotis lagotis).

Among the numerous species of reptiles found here are Desert cave gecko (Heteronotia spelea), Desert death adder (Acanthophis pyrrhus), the Woma (Aspidites ramsayi), and the endemic Red dragon (Ctenophorus rufescens).

Why are rock wallabies so called?

Answer:
Rock wallabies, as their name suggests, live among rock outcroppings throughout this region. These small marsupials, known locally as "monjon", leap easily from rock to rock with the help of the thick pads on their hind feet.
